   * {@link Multimap#asMap}.

   * <p>In general, two multimaps with identical key-value mappings may or may not have the same
   * hash codes, depending on the implementation. For example, two {@link SetMultimap} instances

* The **database model** would probably need to have a hashed password.

/// danger

Never store user's plaintext passwords. Always store a "secure hash" that you can then verify.

If you don't know, you will learn what a "password hash" is in the [security chapters](security/simple-oauth2.md#password-hashing).

     * how to cache them.
     *
     * A typical use case is to hash the request body:

     * ```kotlin
     *     val hash = body.sha256().hex()
     *     val query = Request
     *         .Builder()
     *         .query(body)
     *         .url("https://example.com/query")
     *         .cacheUrlOverride("https://example.com/query/$hash".toHttpUrl())
     *         .build()
     * ```
